Using water to represent the atmosphere and milk droplets to represent aerosols, students make predictions and conduct investigations to discover how different aerosol concentrations affect atmospheric color and visibility. This lesson is one of... (View More) four in the GLOBE program storybook entitled, "What's Up in the Atmosphere? Exploring Colors in the Sky."

Through the use of prisms and glue sticks, this activity introduces students to a fundamental property of light: white light is made up of colors representing different wavelengths. Students use the results of the activity to explain the variation... (View More) in sky color from daytime (blue) to sunset (red).

The effects of gravity on near-surface objects and those in Earth orbit are explored in this activity. A brief explanation, links to three related videos, a teacher's guide and short assessment are included.

Using common items - a glass soft drink bottle, a straw, clay and food coloring - students assemble and calibrate a thermometer and then use it to measure outdoor temperatures. Students record and graph the temperature data and, additionally,... (View More) complete scale conversion problems, a written assignment and an oral presentation. The Students' Cloud Observations On-Line (S'COOL) project engages students in making and reporting ground truth observations of clouds then comparing those observations with data from the CERES satellite instrument.

The total amount of water on Earth, the places in which it is found and the percentages of fresh vs. salt are examined in this lesson. A short demonstration allows students to visualize the percentage differences and a coloring exercise illustrates... (View More) locations. This lesson uses the 5E instructional model. All background information, student worksheets and images/photographs/data are included in these downloadable sections: Teacher's Guide, Student Capture Sheet and PowerPoint Presentation.

In this activity, participants learn about the atmosphere by making observations and taking measurements. They will go outside and use scientific equipment to collect atmospheric moisture data (temperature, relative humidity, precipitation and cloud... (View More) cover). Students will use this qualitative and quantitative data to understand how water is found in the atmosphere, how the atmosphere determines weather and climate, and how Earth’s spheres are connected through the water cycle. The data collection is based on protocols from the GLOBE program. This activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons. (View Less)
